On a coordinate grid, point A is at (−3.0, −5.4) and point B is at (−3.0, 5.4). Point B is a reflection of point A across the __
Eddi Din [679]
Given:
Point A (-3.0,-5.4)
Point B (-3.0,5.4)

reflection across y-axis ⇒ (a,b) reflected (-a,b)
reflection across x-axis ⇒ (a,b) reflected (a,-b)
reflection across the origin ⇒ (a,b) reflected (-a,-b)
reflection on y = x ⇒ (a,b) reflected (b,a)

Point B is a reflection of Point A across the x-axis.

Graph a line with a slope of -2/5 that contains the point (-3,5)
kotykmax [81]

y=-\frac{2}{5}x+\frac{19}{5}

Further explanation:

We have to find the equation of the line first to graph the line.

The general form of slope-intercept form of equation of line is:

y=mx+b

Given

m=-\frac{2}{5}

Putting the value of slope in the equation

y=-\frac{2}{5}x+b

To find the value of b, putting the point (-3,5) in equation

5=-\frac{2}{5}(-3)+b\\5=\frac{6}{5}+b\\5-\frac{6}{5}+b\\b=\frac{25-6}{5}\\b=\frac{19}{5}

Putting the values of b and m

y=-\frac{2}{5}x+\frac{19}{5}

The graph is made by using online graphing tool Desmos.

Keywords: Equation of line, graph of line

Use mental math. A resort has 380 rooms with space for 6 people. Estimate the greatest number of people who could be in these ro
Olin [163]

Answer:

6 people

Step-by-step explanation:

Since the resort has 380 rooms with space for 6 people, only 6 people can be in these rooms at the same time.

Note: It was not said that each room has space for 6 people but the hotel has space for 6 people

Irrespective of the number of rooms available, the space limit is 6, hence not more than 6 people can be accommodated.
